ANGLE FINDER.

Original application filed July 5, 1922, Serial No. 573,025. Divided and this application filed July 6,

This invention relates to new and useful improvements in an angle finder.

This application is filed a divisional application, the subject matter hereof being divided out from application filed by this applicant on July 5, 1922, for a combination tool, under Serial No. 573,025.

One object of the invention is to provide a tool of the character described particularly designed for use by carpenter's for cutting timbers, boards and the like, at such angles that the timbers will fit, when erected, into arches, and it may also be used for cutting timbers designed to be fitted into any desired angles.

Another object of the invention is to provide a device of the character described which is of simple construction and may be cheaply and easily manufactured, and readily applied to the work.

With the above and other objects in view this invention has particular relation to certain novel features of construction, use and arrangements of parts, an example of which is given in this specification and illustrated in the accompanying drawings, wherein Figure 1 shows a plan view of the tool.

Figure 2 shows a side view thereof.

Figure 3 shows a transverse sectional view thereof, taken on the line 8-3 of Figure 1.

In the drawings the numeral 1 designates a blade which is formed with a lateral lengthwise groove 9 one edge of said blade serving as a straight edge as hereinafter exr plained. This blade is shown fitted through a deep lengthwise groove 2 of the block 3. A clamp rod 4 works through a transverse aperture 5 of said block and its outer end is threaded to receive the adjusting nut 6 which works in the slot 7 cut through said block. The other end of the clamp rod 4 has a lateral catch 8 which engages in said groove 9, and this catch holds the blade against detachment from the block. By loosening the nut 6, the blade may be adjusted and by tightening the said nut theblade may be held at any point of adjustment. Pivoted to one end of the block 3 are the arms 10, 10, whose free ends have the upturned catches 11, 11. The block has the lengthwise slot 12, in which a bearing pin 13 is slidably mounted. The slot 12 terminates at one end of an enlargement to receive the head of the pin 13 in assembling the device. Connecting links 14,14, are

Serial No. 650,557.

pivoted at one end to said pin, and at their other ends they are pivoted to said arms. The outer end of the pin is threaded to receive a thumb nut 15, providing for the adjustment of said pin to any desired point in the slot 12. By tightening said nut the pin may be secured at any point of adjustment. The device illustrated in Figure 1 is to be used forcuttingtimbers for the particular construction of arches and the like, and in application for this purpose, the arms 10 may be adjusted to any angle, and there secured and the catches 11 then engaged against the edge of the timber to be cut and a pencil may then be used for drawing a line on the timber along the edge of the blade and the timber when out along said line will have the proper angle to fit into the arch. Then the device is to be used for cutting timber or boards, to fit within an angle, the blade is removed and the arms 10 adjusted into position to fit within the angle, as designated by dotted lines in Figure 1. The edge of the block 3,- is then placed against the edge of the timber to be cut with one arm 10 lying diagonally across the timber, and a pencil drawn along the outer edge of an arm 10. When the timber is out along said line it will have the proper angle for fitting the timbers into the inside angle.

I claim:

1. A combination tool including a block, pair of arms pivoted to one end thereof,

and whose free ends are bent at right angles to the arms to form catches said block having an elongated aperture, a bearing pin slidably mounted in the aperture of the block, means for releasably securing the pin against movement, a pair of links pivoted at the one end to said pin, the other ends of the links being pivoted to the respective arms, said block being provided with a deep groove, a blade fitted into said groove and being adjustable therein and a releasable clamp mechanism for securing the blade against detachment from the block.

' 2. A device of the character described including a block having a lengthwise groove anda transverse aperture, a blade having a lengthwise groove in one side, a clamp rod working through said transverse aperture of said block, a lateral catch carried b one end of said rod which engages in the lade groove, and the other end of said rod being threaded, anzadjusting nut on said threaded means for L releasably securing the same end, said block having a slot to receive said against movement, anda pair of, Links pivnut, a pair of arms pivoted to one end of oted to the respective arms at one end and 10 said block Whose free ends ar e bent at right to said bearing pin at their other ends.

angles to form catches, said block having In testimony whereof, I have signed my an elongated aperture, a bearing pin -sl-idname to this specification.

ably mounted in the aperture of the block, LEWIS J. CHERRY.
